there is no network interface unless "eri" on path_to_inst
but there is network interface ce on path_to_inst ori and path_to_inst.bak

my question :

  1. can i copy it to recent path_to_inst ???
  2. can i set hostname.[interface network] to hostname.ce[xxx] ?

the system has ce Interfaces?
If yes make a reconfigure reboot and then look again. Check the cards, maybe the card is damage or someone remove the cards.
